Arigid tank of 1.1 m3 is divided into two equal compartments by a partition. one compartment contains o2 at 300 k and 100 kpa, and the other compartment contains n2 at 350 k and 200 kpa. now the partition is removed, and the two gases are allowed to mix. the heat gain from the surrounding air at 400 k during this process is 50 kj. determine (a) final mixture temperature, in k, (b) final mixture pressure, in pa, and (c) total entropy production, in kj/k. (cv, o2

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
